The AJAX, formerly known as the Scout SV (Specialist Vehicle), is a program for the British Army to provide a new generation of light tracked armored vehicle. The Scout SV program is lead by the Company General Dynamics UK with the goal to replace the CVRT (light armored vehicle) fleet of the British Army and to be the British Army's Tracked Combat Vehicle Reconnaissance.

The PMRS (Protected Mobility Reconnaissance Support) is the reconnaissance variant of the Scout SV family. In June 2014, at DVD (Defence Vehicle Dynamics), General Dynamics UK has unveiled the first pre-production prototype of PMRS (Protected Mobility Recce Support). The PMRS will provide safe transportation of fully-equipped soldiers in a well-protected environment.
